Maybe we could have a way to open all the TOC and to close it. In the side bar and also in the cover page.

Books with big number of parts, require such option
( I did like it the TOC of the cover page in the old theme, it was big but easy to read. All the information in one screen thanks to the 3 colums, but now we can have bigger titles…yes)

We can increase the font size, but if we change the page, the content is tiny again. Maybe for registered users, we could have the possibility to have the font bigger. So is not necesary to increase the font again and again each time we change the page.

The footer redbar is not in the center of the browser. Is in the center of the screen, but as the browser have the scroll bar, is not in the true center. The true center is the px of the screen - the px of the scroolbar maybe.
